I hope you are not too upset with me but from the outside looking in on the siuation you wrote about even when you step in and stop the behavior and correct the boy he is still abusive in his actions toward your son. Again while there is a lesson to be learned by both boys and only your son most likely will learn anything at all after it continues on and it is repeated, your son tolerates the behavior, and it is abusive on the part of the other child and inflicted onto your son.
I have been there and done that with a little girl and my 10 ten year old DD. You cannot parent someone else's child.
